I thought this was pretty funny, via MediaBistro.

This excerpt from Carrie Fisher’s autobiography is entitled: “Dad ran off with Liz Taylor, Cary Grant lectured me about drugs, George Lucas ruined my life: The extraordinary autobiography of CARRIE FISHER”

Remember the white dress I wore all through that film? George came up to me the first day of filming, took one look at the dress and said: ‘You can’t wear a bra under that dress.”OK, I’ll bite,’ I said. ‘Why?’ And he said: ‘Because … there’s no underwear in space.’

He said it with such conviction. Like he had been to space and looked around and he didn’t see any bras or panties anywhere.

He explained. ‘You go into space and you become weightless. Then your body expands but your bra doesn’t, so you get strangled by your own underwear.’
